Abstract RU 2315830 C1

FIELD: manufacture of knitted products such as knitted filters.

SUBSTANCE: knitted filtering material is made from complex chemical threads having linear density of 90-120 tex by 1x1 rib weave with filling coefficient of 0.50-0.58 determined from formula: k=l/√T, where l is length of thread in stitch, mm; T is linear density of thread, g/km. Fiber surfaces are covered with thiocarbamide and malonodiamide ionizable groups of silicone.

EFFECT: improved filtering quality, increased resiliency of filtering material and high resistance to multiple deformations.
